This is particularly adapted to locate the holes for the handles and latch and the key lock mechanism of automobile door locks, such as shown in the application of Lewis J. Morgan, Sr. No. 536,592, filed Feb. 14th, 1922.

As will be understood by those skilled in the art, the doorlatch and lock mechanism of automobiles is located on the inner side or on the interior of the door, the inner faces of the doors are of different inclinations and the outer faces of the doors are curved, the inclinations and curvatures varying in different doors, although intended to be exactly the same.

In placing the handles on the outer sides of the doors it is highly desirable. it not necessary, to have the shanks of the handles at substantially a right angle to the outer face of the door and also these handles must be located in juxtaposition to the key lock mechanism. This is therefore for the purpose of locating the holesfor the handles and the key mechanism of the lock.

This'jig comprises generally a body or clampingloracket 1 having opposing jaws 2, 3, a locating and clamping member 4: 'X-tending transversely through one aw and adjustable endwisely to clamp the bracket onto'the .automobile'door, as 5, and having .a-bearing iaceb coy ered by suitable pad- Serial No. 594,248.

ding 7 for engaging the faceof the door and a tool guide passage 8 for a tool as a drill 9, tr e passage 8 opening through the bearing face 6 and being alined with the shank of the locating and clamping membe: 4-. Thepassage 8 is formed in a sleeve or bushing suitably mounted in the jaw 3.

lhese locks, such as shown in the pending application referred to, comprise a memher or cam 10 which operates the latch or bolt of the mechanism and also another.

similar member 11 which is key operated and acts to permanently lock the door closed, these two members being located in the easing 12 which is initially attached to the inner side of the door 5.

The usually has a second locating member 13 and also a second guide member 1% carried by an arm 1& and having a passage 15 with the locating member 13; the locating member 1 placing the hole for the handle of the latch mechanism of the lock and the locating member 13 placing the hole for the key lock mechanism which controls the permanent lock member 11.

The locating member 13 is mounted on a part orblock 13 carried by an arm 16 hav ing a hub 16 journalled on the jaw 2 and adjustable about the axis of the locating member 4; and the arm 14c has a hub 14" journalled on the jaw 3 and adjustable about the axis of the tool guide 8. The arms 16 and 14? are adjusted correspondingly about the jaws 2 and 3 respectively, so that the second locating member 13 and the tool guiding passage '15 are always in alinement. As here illustrated, the member 14 is held in its adjusted position by a spring pressed bolt 17 carried in the hub 14 of the member 14: and having a nose 19 movable into any one of two holes 20, usually arranged dia metrically opposite each other in a flange 21 on which the bearing face 6 is pivoted. The bolt is provided with a suitable handle 22 by means of which it may be retracted against the action of its spring 23. The arm 16 carrying the locating member 13 is held in position by asimilar locking'mechani'sm the bolt or which is operated by a'ha'ndle 22,8;- v. V V a "In the illustrated embodiment of our invention, the locating members ar'e'screw; threaded, themember 4;"threa'din'g through the jaws of the bracket 1" and" the locating parallel to the passage 8 and alined loo is placed member 13 threading through the mem ber 13. 7

In order'to space the locating members 4' and 13 different distances apart, the arm 16 is formed with a radial guide 24 and the block member 13 through which the member 13 threads is adjustable along the guide and is held in its adjusted position by a clamping screw 25 which clamps opposite sides of the guide 24 on the block 13". The arm 14 is formed with a similar radial guide 26 for the guide block 14 adjustable along'the guide 26 and held in its position by a clamping screw 28 which operates to clamp opposite sides of the guide onto the block 14.

The locating member 4 is provided with a terminal piece 29 at the end of its shank, which terminal piece is connected to the shank by a universal or ball and socket joint 30, and is secured to the shank by a screw or other fastening device 31 extending endwisely through the terminal piece 29 and threading axially into the shank 4. The passage in the terminal piece 29 for the screw 31 being of such shape as to permit movement of the ball and socket joint. The terminal piece 29 is also provided with a projecting hub or point 32 at its outer end for entering the hole in the member 10 in which the shank of the handle is finally attached, this hole being usually square and the hub 32 being also square to fit therein. The locating member 13 is provided with a conical point 33 at its end, this point being rigid therewith and adapted to enter a hole 34 in the member 11 of the lock, the hole 34 receiving the rod or shaft of which is turned by the key of the key lock which lock mechanism is located by the drill 35 guided in mechanism, in the hole bored the passage 15.

In operation, the casing 12 of the lock on the inner side of the door. 'In order to locate the handles and the key mechansim in alinement with the members 10 and 11 in the casing 12, the bracket 1 is mounted on the door, as shown in Figure 1 with a padding 7 for the bearing face 6 against the outer face of the door and with a terminal piece 29 in the member 10.

Also the locating member 13'is arranged With its point in the hole of the member 11 of the lock mechanism. In so locating the member 13 the locating member 4 will move about the ball and socket joint 30 by so doing,

and properly position or aline the guide passage 8 with the locating member 4 and also locate the passage 15 in alinement with the locating member 13. Both locating members 4 and 13 are then tightened and suitable drills operated in the guide passages 8 and 15 and the holes drilled thereby are in alinement with the locating members 4 and 13 and in proper relation to,

or at the right angle to the outer face of the door and also in proper relation to the holes of the locking members 10 and 11. On different doors, it is necessary to shift the arms 16, 14 about the axis of the locating member 4 and tool passage guide 8. This is readily done by unlocking and swinging the support 16 of the locating member 13 about the jaw 2 until its point 33 can be placed in the hole of the member 11 and locking it in its adjusted position as described; and the arm 14 is likewise unlocked and swings about the jaw 3.

By this jig, the handles of the door latch mechanism of automobiles can be accurately located to stand at the proper angle to the outer faces of the doors.
